ASME B16.11 Forged SS 45° Socket Weld Elbow
Forged Stainless Steel Material Standard: ASME A182
Manufacturing Facility Standard: ISO 9001:2015 , GB/T19001-2016
Certification: Material Test Reports (MTRS) and Certificates of Conformity (COC) are available upon request.
Product Overview
This high-pressure 45 degree socket weld elbow is manufactured to ASME B16.11 standards, designed for demanding industrial applications. The robust sw elbow construction ensures reliable performance in critical piping systems, available in pressure ratings from 3000# to 9000#. This durable 45 degree socket weld elbow features precision-machined socket ends for perfect alignment and secure, leak-proof connections. The sw elbow design facilitates smooth 45-degree directional changes while maintaining excellent flow characteristics. Ideal for high-pressure services in oil and gas, petrochemical, and power generation industries, this reliable 45 degree socket weld elbow delivers superior corrosion resistance and long-lasting performance under extreme conditions.
Key Features
- Extreme Pressure Ratings: Precision-forged to meet the rigorous demands of 3000lb, 6000lb, and 9000lb systems. These fittings are built to maintain safety and performance under the most intense hydraulic and pneumatic loads.
- Superior Socket Weld Design: Features deep, precision-machined sockets that allow the pipe to be inserted and fillet-welded. This creates a robust, permanent connection that is resistant to vibration, thermal expansion, and mechanical stress.
- High-Grade Stainless Steel: Forged from top-tier stainless steel (available in 304/304L or 316/316L) for exceptional resistance to oxidation, pitting, and crevice corrosion—even in highly acidic or saline environments.
- Optimized 45° Flow Path: The gradual 45-degree angle reduces the pressure drop and internal erosion typically caused by sharper 90-degree turns, ensuring a more efficient and stable flow for high-velocity fluids.
- Full Size Range (1/8"to 4"): We offer a comprehensive range of sizes to accommodate everything from small-scale laboratory instrumentation to large industrial production lines.
- Precision Manufacturing: Each elbow is machined to exacting tolerances, ensuring perfect alignment with your piping system. This level of precision simplifies the welding process and guarantees a professional, code-compliant installation.
